Embodiment Construction

[0022]Embodiments of the present invention relate to a cochlear implant electrode lead adapted to implement new storage techniques for excess electrode leads consistent with minimally invasive implantation methods without creating additional storage cavities.

[0023] Figure 4 shows anatomical details of a mastoid channel 400 suitable for excess electrode storage, and Figure 5 Various logical steps in a method of surgically inserting a cochlear implant electrode array according to an embodiment of the present invention are shown. The mastoid channel 400 extends along a longitudinal channel axis 405 from the laterally outer surface of the patient's mastoid bone 404 through the patient's mastoid bone 406 into the middle ear 103 . Initially, in step 501, an enlarged diameter external mastoid tunnel 401 (e.g., about 3.0 mm in diameter) is prepared, which is drilled through the mastoid bone 406 to the facial nerve and tympanum during implantation surgery. The channel (eg, about...

Abstract

An implantable electrode arrangement for a cochlear implant system is described. An electrode lead contains a lead structure control element configured to control a lead shape of the electrode lead between an insertion state wherein the electrode lead within a mastoid tunnel has a longitudinal lead axis lying entirely along the tunnel axis, and a post-insertion state wherein a facial recess portion of the electrode lead fitting within a limited diameter portion of the mastoid tunnel associated with a facial recess portion of the mastoid bone has a longitudinal lead axis along the tunnel axis,and a storage portion of the electrode lead fitting within an enlarged diameter portion of the mastoid tunnel lateral to the facial recess portion has a longitudinal lead axis coiled in a helical shape radially around the tunnel axis.

Description

[0001] This application claims priority to US Provisional Patent 62 / 415,576, filed November 1, 2016, which is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to medical implants, and more particularly, to implantable electrode assemblies for use in cochlear implant systems. Background technique [0003] Such as figure 1 As shown in , the normal ear transmits sound through the outer ear 101 to the tympanic membrane (eardrum) 102, which moves the bones of the middle ear 103, which in turn vibrates the oval and round window openings of the cochlea 104. The cochlea 104 is a narrow, long tube that is wound helically around the axis of the cochlea 104 about two and a half turns. The cochlea 104 includes an upper channel known as the scala vestibuli and a lower channel known as the scala tympani, which are connected by the cochlear duct. The scala tympani forms an upright spiral cone with a center called the modiolus in whi...
